Embodiment 1

[0021] 4 parts of L-threonine, 2 parts of L-arginine, 0.3 parts of L-tryptophan, 3 parts of zinc glycinate, 3 parts of iron glycinate, 2 parts of chromium picolinate, 18 parts of sodium bicarbonate, potassium chloride 5 parts, glucose 15 parts, taurine 8 parts, yeast selenium 3 parts, vitamin C 6 parts, vitamin E 5 parts.

[0022] By adding 0.1% feed additive of the present invention in the diet of weaned piglets, 120 weaned piglets were selected in the test, and single-factor experiment design was adopted, and they were randomly divided into 2 treatment groups by body weight, and the matched group did not add the additive of the present invention. There were 12 repetitions in the group, 5 pigs in each repetition, and the test period was 28 days. The effect of this feed additive on the performance of weaned piglets is shown in Table 1.

[0023]

[0024] The effect of this feed additive on diarrhea in weaned piglets is shown in Table 2.

Embodiment 3

[0033] 3 parts of L-threonine, 2 parts of L-arginine, 0.1 part of L-tryptophan, 3 parts of zinc glycinate, 3 parts of iron glycinate, 2 parts of chromium pyridine carboxylate, 22 parts of sodium bicarbonate, potassium chloride 6 parts, glucose 25 parts, taurine 12 parts, yeast selenium 3 parts, vitamin C 5 parts, vitamin E 4 parts.

[0034] By adding 0.1% of the feed additive of the present invention to the diet of finishing pigs, the growth performance was significantly improved compared with the control group, as shown in Table 5.

[0035]

[0036] See Table 6 for the impact of the feed additive of the present invention on pork quality.

[0037]

[0038] The invention takes weaned piglets and growing-finishing pigs as experimental objects, and applies a nutritional means to relieve the decline in pig production performance caused by weaning stress and various production-related stresses. The above application and test results prove that: the invention slows do...

Abstract

The invention discloses a feed additive for improving pig stress resistance. The feed additive is prepared from the following components in parts by weight: 2-4 parts of L-threonine, 1-2 parts of L-arginine, 0.1-0.3 part of L-tryptophan, 2-3 parts of zinc glycinate, 2-3 parts of ferrous glycine, 1-2 parts of chromium picolinate, 18-22 parts of sodium bicarbonate, 5-8 parts of potassium chloride, 15-25 parts of glucose, 8-12 parts of taurine, 1-3 parts of selenium yeast, 3-6 parts of vitamin C and 2-5 parts of vitamin E. According to the feed additive, adverse effects on health and production performance of pigs caused by various stresses of the pigs in the growth process can be relieved through nutrition means; and by using the additive, the production capacity and the immunity of the pigs can be significantly improved.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive for improving the stress resistance of pigs and an application thereof. Background technique [0002] Stress is a series of non-specific neuro-endocrine reactions caused by various strong stimuli caused by stressors acting on the body, manifested as sympathetic nerve excitement, increased secretion of pituitary-adrenal cortex hormones, and various functions caused by it. , changes in metabolism, including changes in immune function. [0003] Animals are often subjected to various stresses during the production process, including environmental factors, such as heat stress, resulting in reduced feed intake and significantly reduced production performance of growing and finishing pigs; oxidative stress, oxidized oils in feed, various anti-nutrients Factors will destroy the redox balance of the body, so that the pigs suffer from oxidative stress; weaning stress, the una...
